# Undefined control sequence .<recently read> \aline( in a table) [closed]

Heelo, I am getting this error note but the document still compiles, however, the table of contents does not and I kind of need it.

The part where the error lies is:

\subfloat[Subtable 3 list of tables text][Mayor proporción de bajos ingresos]{
\begin{tabular}{l|ccc}
\aline
$c_1$ & 5.7143  \\
$c_2$ & 12.8571 \\
$q_1$& 1.2857\\
$q_2$& 2.5714\\
T& 4.2857 \\
U & 1.2478 \\
\end{tabular}}

In particular the last line.

Any ideas?

• Welcome to TeX.SX! Please make your code compilable (if possible), or at least complete it with \documentclass{...}, the required \usepackage's, \begin{document}, and \end{document}. That may seem tedious to you, but think of the extra work it represents for TeX.SX users willing to give you a hand. Help them help you: remove that one hurdle between you and a solution to your problem. – cfr Aug 15 '14 at 23:48
• What is \aline? Perhaps you meant \hline? – cfr Aug 15 '14 at 23:48

I think, you use package subfig and you want to underline head of table.

\documentclass[10pt,a4paper]{article}
\usepackage{subfig}
\begin{document}
\begin{figure}
\subfloat[Subtable 3 list of tables text][Mayor proporción de bajos ingresos]{
\begin{tabular}{l|ccc}
$c_1$ & 5.7143  \\
$c_2$ & 12.8571 \\
$q_1$& 1.2857\\
$q_2$& 2.5714\\
